pcbit: drop unusable remnants

With the un-distributable confhexbin.c file, that provided the essential
function convhexbin(), gone, it is not sensible ito keep the ruins that
do not compile any more.

Thanks to git, the 'pcbitctrl' utility can get resusitated once someone
writes a free convhexbin() routine that is compliant to the unfree one..
Until then: R.I.P.
